- Parker Model: AdiabaticAdiabatic descrie un sistem sau un mod de măsurare fără niciun schimb de căldură cu mediul înconjurător. Acest mod poate fi realizat utilizând un dispozitiv calorimetric în conformitate cu metoda calorimetriei cu rată de accelerare (ARC). Scopul principal al unui astfel de dispozitiv este de a studia scenariile și reacțiile termice scăpate de sub control. O scurtă descriere a modului adiabatic este "nu intră căldură - nu iese căldură".Adiabatic Conditions
